Specification of Letters Patent.

Application led May 4, 1908. Serial No. 430,684.

make 'and use the same, vreference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an im rovement in a manually operated appliance or atomizing or spraying liquid disinfectants or insecticides.

The object of this invention. is to place upon the market a device simple andmex ensive in construction and one which may ereadily cleaned or repaired. The invention also relates to certain details of conof the plunger rod belng of struction described in the following specificationand claims and shown in the accom-r panying drawings in which2- i Flgure 1 is a vertical central section through the device with partsbroken away. Fig. 2 yis a fragmentary view in elevation and section showing the 'invention mounted on ay glass canning jar.

Referring nowto the letters of referencev placed upon the drawings: A denotes a` closed receptacle provided with an opening fitted with-a threaded collar or cap Bf.

C is a chambered casting mounted upon and secured to the cap B. n D is anl air pump cylinder its forward tapering end secure to a boss c formed in the casting C:

D is the pump plunger, D2 the plunger rod, andDs its o eratinghhandle. D4 is a cap c osingt erear end ofthe pump cylinder, the opening d for the passage sufficient dlameter to admitair into the cylinder.

E is a projecting pin set in the bossI cA to limit the forward movement of the plunger Df. 11F is a spray tube secured lat oneend to i the casting C and provided at its forward within the spray wher-extending e end ywith a removable perforated cap or nozzle F.

G is. an L-shaped deliyery tube upported from the bottom portion of the receptac point near, the end of the spraytube.

H is a chamber in the casting C opening into the body of the receptacle A and afford- A to a' ing communicationbetween the latter and the spray tube F. The casting C is also formed with a cylinder H, closed at its forward end by a screw H2, but at its rear end l o eningdirectly into the ump cylinder D,

t rough which wall it projects.

H3 is a ort for the passa e of air from the cylinder to the chamber y I is a check valve located in the cylinder H', and seating against its contractedv portion h:-thefrelat1vely long stem'i of the valve acting in conjunction with the contracted portion of the cylinder to guide the valve to its seat.

4J is a screw supported in the wall of the cylinder H its inwardly projecting end servin to limit the movement of the valve I.

aving indicated the several arts by reference letters, theoperation of t e appliance will be readily understood. The cap with its connectingparts is first unscrewed from the receptacle`A, the can is then charged with the re uired liquid disinfectant or insecticide an the parts replaced as before. The pump plunger is now driven forward by means ofits operating handle, forcing the air admitted through the opening d past the check valve I through the port Hf mtothe receptacle A putting the liquid therein under pressure. U on the return stroke' of the plunger the chec valve I is forced to its seat due to the air pressure inI the receptacle and side of the valve bythe movement of the Hump, plunger. The air in the chamber A aving been put under sufficient pressure' by the actionof the pump, the liquid is forced out through the delivery tube G where it is met and atomized by the blast of compressed air seeking to escape through the spray tube F. In order to provide for projecting the spray in any desireddirection the removable cap or nozzle F is mounted on the end of the spray tube, the openings in the cap being such as will direct the spray in any directionrequired. -It 'willfbe seen that by providing a pum of sufficient capacitythe air in the receptac e maybe ke t under sufficient pres.- sure so that the disc argeof thedisinfectant or insecticide will be continuous, irrespective of the direction in which the pump plunger may at the moment be moving.

I desire to draw articular attention to the fact that the checl() valve employed to control the air in the chamber may be readily removed either for cleaning, repairs or replacyso in with a-new valve as required,-it being o y necessary to remove the screws H2 and J to effect this result. In fact it will be noted that all the parts are easily accessible either for cleaning or repairs.

In Fig. 2. of the drawings I have shown the device applied to an ordinary canning jar of the Mason type,-when used'in this connection a cover` ada ted to fit this style of jarl is provided to Whic the parts are secured.
